The shoe includes an upper. An outsole has an upper edge end provided on an upper sole part, an air chamber provided inside the upper edge end, and an ascending and descending edge surface provided on an outer edge of a lower sole part in such a way as to be inclined outwards and upwards from a bottom surface, the outer edge of the lower sole part being provided under the upper edge end to be opposite thereto. An insole is secured to the upper edge end to cover a top of the air chamber, with a plurality of ventilation holes being formed in a front portion thereof. A backflow prevention valve prevents outside air supplied to the air chamber from flowing backwards. An air inlet pipe supplies the outside air to the backflow prevention valve.

[KIM BYUNG NAM, JANG WON JUN] KR;KR;KR The present invention relates to an emergency power supply system performing a function to automatically supply power of an emergency battery with accumulated power to a load when an outage occurs, optimizing a power supplying function of the battery through stable control of power accumulation and an overcurrent and overvoltage protecting function of the battery where power is accumulated, and when performance of the battery becomes deteriorated, automatically regenerating the battery to improve the power accumulation function, thereby remarkably increasing the product′s life span. The emergency power supply system comprises: a power supply part converting alternating normal power, which is supplied to the load, into predetermined direct current voltage in order to charge a batter part; a solar power collecting tube dropping generated electrical energy into predetermined direct current voltage through a voltage drop part to apply charged voltage to the battery part; the battery part charged by power supplied from the power supply part and the solar power collecting tube; an alternating current (AC) power detecting part detecting AC power applied to the load to provide outage emergent state information to a control part; the control part detecting a value input into the AC power detecting part, discharging the battery part when a load outage occurs in order to emergently supply the power of the battery part to the load; a battery management part preventing overvoltage, overcurrent, and over-discharge of the battery part under a control of the control part, controlling stable charging and discharging of the battery part, and transmitting a charged amount to a control part; and a battery generating part regenerating the battery part under the control of the control part when the performance of the battery part becomes deteriorated in order to recover the battery function.

[Ho-Min Son, Yong-Woo Hyung, Won-Jun Jang, Jung-Geun Jee, Hyoeng-Ki Kim] KR Suwon-si A method of fabricating a nonvolatile memory device includes forming at least one insulating layer on at least one of a semiconductor substrate and a layer including a semi-conductive material, and performing a plasma process using fluorine on the semiconductor. In some cases, an interface between the insulating layer and the semiconductor substrate includes fluorine.

Then the adjacent field isolation regions is etched to increase the width of the opening.

[JANG WON JUN] KR The present invention relates to a deburring device and a deburring method using the same, and more particularly, to a deburring device capable of efficiently removing the burrs of an injection molding article generated when manufacturing by injection molding by a die casting method, and a deburring method using the same. The present invention exerts the following effects. According to the present invention, the burr removal time is significantly reduced compared to a conventional deburring method using a hand tool so that the productivity is improved and the injection molding article is not moved to accurately remove only the burr of the injection molding article and to ensure the uniformity of quality, thereby improving product satisfaction from customers.

The ventilated shoe (10) of the present invention consists essentially of: a ventilation tube (20), which is installed in a lower portion of the interior (11) of the shoe (10) and which has an elastic upper surface (21) and an elastic lower surface (22) formed into a single body such that a front air chamber (23), the shape of which is restored after being pressed, is formed between the upper surface (21) and the lower surface (22) thereof and an expanding rear air chamber (231) having a volume larger than that of the front air chamber (23) is formed in a rear portion of the ventilation tube (20); a ventilation means (24) arranged at the front side of the upper surface (21) of the ventilation tube (20) such that air in the air chamber (23) may pass into the interior (11) of the shoe (10); a suction hole (31) formed at the rear of the lower surface (22) of the ventilation tube (20); a backward flow prevention means (30) for preventing the air in the air chamber (23) introduced through the suction hole (31) from flowing backwardly through the suction hole (31); an elastic member (40) arranged in the expanding rear air chamber (231) so as to compulsorily expand the rear portion of the ventilation tube (20); an air guide path (50) in which an elastic guide member (51) is attached to the rear of the lower surface of the ventilation tube (20) to guide air to be suctioned through the suction hole (31); and an air suction tube (60) connected to the air guide path (50) and fixed upright to be supported at a rear member (12) of the shoe (10) so as to suction outside air.

[JANG CHANG WON, WON JUN YEON] KR;KR PURPOSE: A ventilating shoe which pumps by using an outsole is provided to be ventilated only by a liner and an outsole without a pocket. CONSTITUTION: A ventilating shoe which pumps by using an outsole comprises an outsole(10), an insole(20), a backflow prevention valve(30), and an air inlet(40).The outsole comprises an upper edge unit which is installed at the upper part of the sole, an air chamber which is included in the inner side of the upper edge unit, and an ascending and descending edge unit which is inclined towards the upper outer side from the floor. The liner is fixed to the upper edge unit to close the upper part of the air chamber and has a plurality of ventilation pores in the front. The backflow prevention valve prevents backflow of air after providing air to the air chamber. The air inlet provides external air to the backflow prevention valve.
